Earth Elemental

Any Stronghold native heroes that have acquired Dragonblood crystals will allow the Magic guilds of all Stronghold native towns owned by the player to summon Earth Elemental creature group to the garrison every week on day 1. The amount depends on the Dragonblood crystals heroes have collected (A) and the experience level of those heroes (B). Formula = SQRT ( sum(A*B) ) * ( 3+Guild level ) / 12 rounded to the nearest integer. The amount is zero if no crystals are collected. Creature group moral is neutral.
